Phase III: Implementation and Operation of the Repository

Description: The metadata catalog was brought online for public access May 14, 1998. Since then dozens of users have registered and began to access the system. The system was demonstrated at the AAPG annual meeting in Salt Lake City and the EAGE (European Association of Geoscientists and Engineers) annual meeting in Leipzig, Germany. Hart Publications and PTTC �NetworkNews� have published articles about the metadata catalog, and articles for the AAPG Explorer and GSA Today are being developed. A back-up system at AGI headquarters was established. In support of the metadata catalog system, a leased-line Internet connection and two servers were installed. Porting of the GeoTrek server software to the new systems has begun. The back-up system will be operational during the 3 rd quarter of 1998 and will serve the NGDRS needs during periods when access to the site in Houston is down. Additionally, experimentation with new data types and deployment schemes will be tested on the system at AGI. The NGDRS has picked-up additional endorsements from the American Association of State Geologists, the MMS Outer Continental Shelf Policy Committee, and a new endorsement is being formulated by the AAPG Core Preservation Committee for consideration by the AAPG Executive Committee. The Texas Bureau of Economic Geology (BEG) is currently geocoding the well locations for the metadata catalog. Also, they have solicited proposals for the development of a core inventory control system that will work hand-in-hand with GeoTrek. A contract for that system will probably be given during the 3 rd quarter of 1998. The Texas Railroad Commission proposes to test the application of GeoTrek for accessing data in a joint project with the BEG. Several data transfer projects are underway. Vastar has committed to the transfer of 2D Appalachian seismic lines to the NDGRS clearinghouse. Receiving repositories have been identified and ...

Phase III: Implementation and Operation of the Repository

Description: All of the hardware is installed and all available databases are loaded into the metadata repository. The final stages of beta testing of GeoTrek and necessary revisions are underway, with a targeted public release of the NGDRS system in April or May 1998. The Eastern Gulf Region PTTC, Oklahoma Geological Survey, and A2D databases have been converted and loaded into the metadata repository. These are in addition to the four previously installed databases, including the BEG, MMS, PGS, and Fairfield. Data quality improvements, particularly with the MMS and BEG data is continuing, including making the data more intuitive for the typical user. The beta-testing process has resulted in a number of action items that have been reviewed and addressed. Most of these issues have been resolved, and the remaining issues will be resolved early in the second quarter of 1998, leading to the public launch of the NGDRS metadata repository. Installation of GeoTrek at the BEG, in an effort to bring their core holdings into the NDGRS, was completed in December. A review was held concerning the experiences of the BEG with GeoTrek during January. The feedback was largely positive, with only a couple technical details to address. A number of companies have also expressed interest and/or are evaluating PetroTrek, the commercial version of GeoTrek. Thus far, most of those companies, including PGS and Fairfield, which have licensed PetroTrek have simultaneously joined the NGDRS as well. Several data transfer efforts are underway. Vastar has committed to the transfer of 2D Appalachian seismic lines to the NDGRS clearinghouse. Receiving repositories have been identified and the final preparations are being made for transfer to these public repositories. Additionally, discussions continue with the Stapleton Development Corporation concerning the transfer of facilities in Denver for use as a central core repository.

Phase III: Implementation and Operation of the repository

Description: In October all three Sun servers (3000, Ultra/II) were loaded, and we were able to demonstrate the complete system � databases, web front-page, and GeoTrek � to a large audience. All systems required for the web-based metadata catalog are in place and operational. Version 54 of the PetroTrek/GeoTrek software was loaded in December and is being tested. It is expected this version will be placed in the production environment for beta testing in January. Installation of the Bureau of Economic Geology (BEG) databases on the IS Houston server was completed and GeoTrek was loaded on BEG�s server in Austin. Installation of the entire MMS well data set (35,000 records) was completed and it will be moved to the production environment for beta testing in January. The Eastern Gulf Region PTTC interior salt basin data set was prepared and it will be loaded in January. The Gulf of Mexico PGS seismic data set was prepared and loaded in December. The web-site front pages for the NGDRS GeoTrek Metadata Catalog are 70 percent completed and write-ups for the tutorials are scheduled to be completed in January. Ten users identified to be beta testers are actively testing the system.

Calibration of the MACHO photometry database

Description: The MACHO Project is a microlensing survey that monitors the brightnesses of -60 million stars in the Large Magellanic Cloud (LMC), Small Magellanic Cloud, and Galactic bulge. The database presently contains more photometric measurements than previously recorded in the history of astronomy. We describe the calibration of the MACHO two-color photometry and transformation to the standard Kron-Cousins V and R system. This allows for proper comparison with all other observations on the Kron-Cousins standard system. The highest precision calibrations are for -9 million stars in the LMC bar. For these stars, independent photometric measurements in field-overlap regions indicate standard deviations {sigma}{sub V} = {sigma}{sub R} = 0.020 mag. Calibrated MACHO photometry data are compared with published photometric sequences and with new Hubble Space Telescope observations. We additionally describe the first application of these calibrated data: the construction of the �efficiency� color-magnitude diagram which will be used to calculate our experimental sensitivity for detecting microlensing in the LMC.

Description: This project generates and provides coal samples and accompanying analytical data for research by DOE contractors and others. The five-year contract has been completed and a six-month no-cost extension is under way; this will continue the limited distribution of samples and data to DOE, its contractors and grantees. All activities specified under the five-year contract have been completed. Eleven DECS samples were collected, processed to a variety of particle sizes, heat-sealed in foil laminate bags under argon, and placed in refrigerated storage. All were analyzed for basic chemical composition, inorganic major and trace element composition including hazardous air pollutant elements, petrographic composition and characteristics, thermoplastic behavior (if applicable), and other properties relevant to commercial utilization. Most were also analyzed by NMR, py/gc/ms, and a standardized liquefaction test; trends and relationships observed were evaluated and summarized. Twenty-two DECS samples collected under the previous contract received further processing, and most of these were subjected to organic geochemical and standardized liquefaction tests as well. Selected DECS samples were monitored annually to evaluate the effectiveness of foil laminate bags for long-term sample storage. Twenty-three PSOC samples collected under previous contracts and purged with argon before storage were also maintained and distributed, for a total of 56 samples covered by the contract. During the five years, 524 samples in 1501 containers, 2075 data printouts, and individual data items from 30327 samples were distributed. In the subject quarter, 45 samples, 101 data printouts, and individual data items from 1237 samples were distributed. Splits of the last two samples from the previous contract received processing to minus 0.25 mm; all DECS samples are now available for immediate distribution at minus 6 mm (-1/4 inch), minus 0.85 mm (- 20 mesh U.S.), and minus 0.25 mm (minus 60 mesh U.S.). The final annual monitoring of foil laminate bag ...

The Sloan Digital Sky Survey data acquisition system, and early results

Description: The Sloan Digital Sky Survey will systematically map one- quarter of the sky, producing detailed images in five color bands and determining the positions and absolute bright- nesses of more than 100 million celestial objects. It will also measure the redshifts of a million selected galaxies and of 100,000 quasars, yielding a three-dimensional map of the universe through a volume one hundred times larger than that explored to date. The SDSS collaboration is currently in the process of commissioning the 2.5-meter survey tele- scope. We describe the data acquisition system used to record the survey data. This system consists of twelve sin- gle board computers and their associated interfaces to the camera and spectrograph CCD electronics, to tape drives, and to online video displays, distributed among several VME crates. A central UNIX computer connected to the VME crates via a vertical bus adapter coordinates the sys- tem and provides the interface to telescope operations. We briefly discuss results from the observing runs to date and plans for the archiving and distribution of data.

ATGC: a database of orthologous genes from closely related prokaryotic genomes and a research platform for microevolution of prokaryotes

Description: The database of Alignable Tight Genomic Clusters (ATGCs) consists of closely related genomes of archaea and bacteria, and is a resource for research into prokaryotic microevolution. Construction of a data set with appropriate characteristics is a major hurdle for this type of studies. With the current rate of genome sequencing, it is difficult to follow the progress of the field and to determine which of the available genome sets meet the requirements of a given research project, in particular, with respect to the minimum and maximum levels of similarity between the included genomes. Additionally, extraction of specific content, such as genomic alignments or families of orthologs, from a selected set of genomes is a complicated and time-consuming process. The database addresses these problems by providing an intuitive and efficient web interface to browse precomputed ATGCs, select appropriate ones and access ATGC-derived data such as multiple alignments of orthologous proteins, matrices of pairwise intergenomic distances based on genome-wide analysis of synonymous and nonsynonymous substitution rates and others. The ATGC database will be regularly updated following new releases of the NCBI RefSeq. The database is hosted by the Genomics Division at Lawrence Berkeley National laboratory and is publicly available at http://atgc.lbl.gov.

WebDB Component Builder - Lessons Learned

Description: Oracle WebDB is the easiest way to produce web enabled lightweight and enterprise-centric applications. This concept from Oracle has tantalized our taste for simplistic web development by using a purely web based tool that lives nowhere else but in the database. The use of online wizards, templates, and query builders, which produces PL/SQL behind the curtains, can be used straight ''out of the box'' by both novice and seasoned developers. The topic of this presentation will introduce lessons learned by developing and deploying applications built using the WebDB Component Builder in conjunction with custom PL/SQL code to empower a hybrid application. There are two kinds of WebDB components: those that display data to end users via reporting, and those that let end users update data in the database via entry forms. The presentation will also discuss various methods within the Component Builder to enhance the applications pushed to the desktop. The demonstrated example is an application entitled HOME (Helping Other's More Effectively) that was built to manage a yearly United Way Campaign effort. Our task was to build an end to end application which could manage approximately 900 non-profit agencies, an average of 4,100 individual contributions, and $1.2 million dollars. Using WebDB, the shell of the application was put together in a matter of a few weeks. However, we did encounter some hurdles that WebDB, in it's stage of infancy (v2.0), could not solve for us directly. Together with custom PL/SQL, WebDB's Component Builder became a powerful tool that enabled us to produce a very flexible hybrid application.

Metadata based mediator generation

Description: Mediators are a critical component of any data warehouse, particularly one utilizing partially materialized views; they transform data from its source format to the warehouse representation while resolving semantic and syntactic conflicts. The close relationship between mediators and databases, requires a mediator to be updated whenever an associated schema is modified. This maintenance may be a significant undertaking if a warehouse integrates several dynamic data sources. However, failure to quickly perform these updates significantly reduces the reliability of the warehouse because queries do not have access to the m current data. This may result in incorrect or misleading responses, and reduce user confidence in the warehouse. This paper describes a metadata framework, and associated software designed to automate a significant portion of the mediator generation task and thereby reduce the effort involved in adapting the schema changes. By allowing the DBA to concentrate on identifying the modifications at a high level, instead of reprogramming the mediator, turnaround time is reduced and warehouse reliability is improved.

Publist - a bibliographic database utility

Description: A few years ago, the Department of Applied Science perceived a need to automate activities related to publications by using some computer based system. Among the objectives were that: (1) it should be easy for a secretary or someone without extensive computer skills to use the system; (2) it should run on PCs (at that time DOS based), Macintosh, and Unix systems, so that different groups or individual investigators could use it on their platform of choice; (3) it should be flexible enough to track evolving views of what information was needed; (4) it should be able to generate output in different formats for different purposes; (5) the information should be able to be selected from and sorted by a wide variety of keys; and (6) individual items should be able to be updated with new information or deleted. This document gives an over view of the PUBLIST database for handling bibliographic data.
